2b all whom 'it may concern:

Be it known that I, JONAS NoR'rHRor, a citizen of the United States,residing at Hopedale, in the county of lVorcester and State ofMassachusetts, have invented an Improvement in Shuttle-Boxes, of whichthe following description, in connection with the accompanying drawings,is a specification like letters on the drawings representin like parts.

he invention to be hereinafter described relates to looms, and moreparticularly to the means employed for bringing the shuttle to rest inthe shuttle box at the end of its picking movement.

As well understood by those skilled in the art, the shuttle is picked orthrown from one side of the la to the other in laying the llin in theshe and, as it passes into the shu e box, it is not only desirable thatit be gradually brought to rest in proper po- 'tion in the box, but thatit be not deflected from its straight course as it passes into the boxunder the control of the checking means.

'With these facts in mind, the aims and urposes of the present inventionwill best he understood and made clear from the following deseri tionand accompanying drawings of one orm or embodiment of means for carryingthe invention into effect and seeurin the objects above stated, it beingunderstood that the invention is not restricted to the details shown,but is definitely setfortli in its true scope by the claims.

In the drawhi Figure 1 is a plan or top View of a s uttle box embodyingthe present invention, only so much of the adjacent loom parts beingshown as are necessary to make clear the association and action of theinvention therewith; F ig. 2 is a section on the line 2-2, Fig. l; andFig. 3 is a view similar to that of Fig. l, some of the ports being insection or broken away, and the shuttle being indicated :is having fullyentered the box.

Mounted on the luy beam l is the fixed wall 2 extendin in prolongationor in the lane of the reed and forming a part of the ack wall of theshuttle box. Adjustnbly secured to the lay beam is the front wall 3 ofthe shuttle box, said front wall being preferably provided with theslotted lugs 4 which are engaged by bolts 5,-whereby said A front wallis secured in position. It will .Y be noted that the front wall 3 hasits inner or shuttle engaging surface formed slightly flaring at theent-rance to the shuttle box, said flaring portion G extending from apoint 7, between which and the surface of the back wall 2 the dimensionof the shuttle box is substantially the same as the exterior dimensionof the shuttle. From the point 7 to the terminal portion 8, the shuttleen a g surface of the front wall of the shutetdx is arallel to the innersurface of the back wa b2, the construction bei such that as the side ofthe shuttle ridesriong the inner surface of the back wall 2 of theshuttle box and contacts with the inner surface of the front wall at thepoint 7, the shut-tle continues to travel in a straight course Vandglides straight into the shuttle box, avoiding any side deviation orblow by the rear end of the shuttle against the reed or rear wall of theshuttle box even after the shuttle comes under the influence of itschecking means, as will presently appear.

liovable ,longitudinally in the bottom slot 9 of the shuttle box is thepicker stick l0, of any usual character, the end rtion only of saidstick being shown, an on or connected to the picker stick is the icker11 having a shuttle engaging seat 12, 1, and by which the shuttle isgiven its icking movement, as well understood. I desired, a cushion orbuffer 13 may be connected to the outer portion of the shuttle boxagainst which the picker stick may rest prior to its picking movement.

The. shuttle binder comprises the body portion 14, refer-ably formed ofwood or other desir-eil material, terminating at its inner end portionin a tongue 15, against the exterior surface of which bears the binderfinger 1G for controlling the dagger 1T in a manner well understood bythose skilled in the art, the construction and relation of parts beingsuch that when the shuttle binder is forced buck by the enteringshuttle, it. will more the binder linger 16 and rai-:sc the da ger 17 sothat in the beatup movement. o? the lay the dagger will not engage thetrip member of the knockoli' mechanism, as usual; but should the shuttlefail to enter the shuttle box suiicieiitly far to thus move the binder,or if it should undulv rebound, then the binder will fail to be held inback position as the lay i beats up, with the result that the binder .ifinger will not lift the da ger, and the latter will knock-olf the oom,in the well understood manner.

Passing throu h the outer end ortion of the lay beam ors uttle box is abo t 18 preferably passinor also through a lug 19 of a bracket 20 an thetop plate of the shuttle bx, substantially as indicated by Fig. 2,whereby the top plate and bracket20 :nay be conveniently secured 1nplace, it being understood that while this assemblage of parts is a goedpractical form of means, yet the invention is not restricted thereto.

In the presented form of the invention the outer end portion of thebinder is preferably made of metal, cast or otherwise formed, with theelongated slot 21 which loosely embraces the lug 19 of the bracket 20,Figs. 1 and 3, and having the front and back walls 22 and 22",respectively, between which the body rtion of the binder 14 projects,and to w ich it may be seciued by suitable fasteners or screws 23 and 24or otherwise, as will be clear from Fig. 3. For

ur ses of identification this 'end of the Eindzi', which is connected tothe lay beam or shuttle box, may be called the binder head, itunderstood that the term is used in its road sense for purposes ofdesignation only.

Screw-threaded into the back portion of the binder head is an adjustingscrew 25, the end of which may be positioned in the elongated slot 21,to vary the amount kof lae and forth monentuof the pinder ea for aurpose t wi present y appear, a locli) nut 26 being preferably ernployedto hold the adjusting screw in adusted 'tion irojectiiiogS1 rearwardfrom the end of the lay beam or shuttle box is the bracket arm 20,having the post 28 through which ex tends the screw 29, the inner endthereof being received by a cap piece 30, and a lock nut 1 beingpreferab y em loyed to maintain the-screw 29 in ad}ust position.Disposed between tlie ca piece 30 and the seat 32 on the binder head 1sthe tension spring 33, the construction being such that while thebinder` head is movable toward and from the plane of the front wall ofthe shuttle box y reason of the elongated slot 2l, it is normallyresisted in such movement by the spring 33, as will be evident.

The binder has a swell or inwardly extending portion 34, which, when theshuttle is not in its box, projects into the shuttle box, Fi 3, underthe action of the sprin 33 and ginder finger, and the end of the ajusting screw 25 bears upon the adjacent portion of the bearin lug 19,said screw and the tongue 15 thus eterminin the normal position of thebinder when t e shuttle is 5 not in its box.

As well understood by those familia-1' with the art, it is desirable tobring the shuttle gradually to rest in )roper position in the shuttlebox without shock or injury thereto, und while thc ordinary swellcontributes to this end itis not always satisfactory for well knownreasons. In the present invention the outer end portion or head of thebinder is connected to the lay by the shifting fulcrum and is providedwith the cani surface 35 adapted to act upon the side of the picker 11,as the latter is moved to the end of its outer position by the incomingshuttle, and, as the picker is conned to travel in a straiht line, thebinder head is moved back against the direct action of the sprin 33,imparting to the picker a progressive y increasing retardation as thepicker nieves along the cam surface 35 to the end of its travel. It willbe evident, of course, that the retarding effect of the binder head uponthe picker may be varied bv adjusting the tension of the s ring 33, andthat the amplitude of outwardp movement, and pel-force the retardineiect of the binder head, may be further a justed by means of the screw25.

The present invention is not intended to be confined to the detailsillustrated and described as one form of means for carryinv it intopractical effect, as it ma be modified in various ways by those skilledyin the art.

From the characteristics of the invention as hereinbefore announced, itwill be noted that as the shuttle enters the box it will move in astraight course into position between the back wall and the point 7 ofthe front wall, and as it meets the swell 34 of the binder its straightcourse will not be altered, but the binder will move pivotally about theluv 19 as a. center, thus acting through the abinder linger 16 to raisethe dagger. As the shuttle meets the picker, which is at the timelocated approximately as indicated in Fig. l, it will cause the pickerto move to the right, Fig. 3, with the result that, as the icker movesalong the cam surface 35 of t 1e binder head, the latter will he movedoutward against the tensionof the spring 33, imparting throuvh thepickera procressii-ely increasing retardation to the shutte movement asthe picker approaches the end of its outward travel. During this outwardmovement of the binder head, the binder will turn about a point on theswell in cont-act with the shuttle, but, as the binder swell has itsshuttle contacting portion relatively near the inner end part of thebinder, such action will not interfere unfavorably with the properaction of the binder finger, and tbe parts will come to rest insubstantially the relative position indicated by Fig. 2. It will also benoted that the shuttle contacts with the binder at the binder swell onlyand that the final checking action of the binder operates through the'picker und not directly on the shuttle exco t in so far asi-.outwardmovement of the inderhead may increase the action of the binder'swell.

The action ofthe cam 35 on the picker is liable to 'cause the pickerstick to be'v deflected sidewise toward the o posite wall of the slot 9.As one means o counteracting this tendency, the wall of the slot 9opposite the cam 35 is faced with a suitable material, such as leather36, Fi 1 and 2, which may be preferably thinne toward the in ner end ofthe shuttle box, as indicated in Fig. 1, to properly resist the sidethrust of the pam 35 on the picker stick. Obviously7 also the binder andfront wall of the shuttle box may be faced with any desired material,such as leather.

From the described embodiment of the iiivention it will be seen that thebinder is mounted on a. shifting ulcrum; that the slot 21 in the binderhead is made of suitable dimension to permit the binder head not onl tomove directly outward against the action ,of the spring 33 in the mannerstated, but also to swinfr the necessary amount about the lug 19. tltwill also be noted that as the picker stick moves to the outer portionof its stroke the guiding slot 9 narrows to maintain the icker stick inproper position and to enab e the cam 35 to act effectivgly upon thepicker in checking the shutt e.
